SPEGIFICATION' forming part of Letters Patent No. 513,182, dated January 23, 1894.

Application filed March 13,1893- Serial No. 465,836. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM V. L. GRUBB and JOSHUA FEELING, citizens of the United States, residingin Columbus, Franklin county, Ohio, have invented a certain new and useful Improvement in Bolts; and we do hereby declare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Our invention relates to a bolt, which, unlike other bolts, is used by inversely placing it in position, and when thus placed in such position, the head of said bolt is formed by certain contrivances automatically acting.

The object of our invention is to devise a bolt which can be used in an inaccessible place where it is not possible to insert the bolt in the ordinary way.

In the accompanying drawings Figure 1 shows a side view of said bolt b (a section of the same .being removed), showing the spring e and the pin (1, which together tip the head a of the bolt, and the pin c on which the head a turns. Fig. 2 shows the position of the bolt after the same has beeninserted through the,wood f from below g, and the lowest portion of the head of said bolt hasjust emerged from the top surand turned up to the position as shown in 0 Fig. 2 which at the same time brings down the head of the bolt tightly upon the top of the wood f. Fig. 3 exhibits abackview of the bolt.

We claim as our invention and desire to se- 45 cure by Letters Patent- In combination a bolt, screw-threaded at one end and provided at the other end with a slot, and a recess opening into said slot, a

spring-pressed pin located in said recess, and 50 a head pivoted in the slot having one end beveled to be engaged by said spring pressed pin, substantially as set forth.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures 5 5 in presence of two witnesses.

W. V. L. GRUBB. JOSHUA FEELING.
